PURPOSE: An RFID(Radio Frequency Identification reader) for supporting a dual band is provided to syntagmatically recognize information in various frequency bands by exchanging information with an RFID reader through different frequency bands. CONSTITUTION: One or more ferrite cores(20) are inserted into an inside transmission and reception body unit(10). An identification information transmission unit(31) covers an outer surface of the transmission and reception body unit. Identification information reception units(321,322) are separated from the identification information transmission unit. The identification information reception units cover the outer circumference of the transmission and reception body unit. |
